Industrial Hygiene Testing Services
AIHA-accredited (LAP-101470) industrial hygiene testing laboratory in Houston, TX — 19 IH testing services covering air quality, water, metals, chemical exposure, noise and heat stress, with rush turnaround options and ship-in service from anywhere in the U.S.
Industrial hygiene testing is how a suspected workplace exposure becomes a number that OSHA, an insurer or a court will accept. It covers the air workers breathe, the water in building systems, the dust on a jobsite and the residues left on surfaces — and every hazard carries its own validated method, sampling medium and permissible exposure limit. Get the method wrong and the result answers a question nobody asked.
AGT Labs runs 19 of those testing services from a single AIHA-accredited Houston laboratory (LAP-101470), for construction, manufacturing, petrochemical and healthcare clients across the United States. We are the analytical laboratory — you or your consultant collect the samples, and we analyse them.
With AIHA accreditation (LAP-101470) under both the Industrial Hygiene and Environmental Microbiology programs, and advanced in-house instrumentation — ICP-AES, GC/FID, GC/MS, GC/ECD, HPLC, XRD, IC, UV-VIS, CVAA, and gravimetric microbalance — our team performs detailed IH analysis for asbestos, crystalline silica, metals in air, welding fumes, VOCs, mold, Legionella in water, mercury vapor, aldehydes, isocyanates, PAH, PCB, and other chemical or biological hazards. Every analysis follows validated OSHA, EPA, and NIOSH methods under ISO/IEC 17025 quality management.
Whether the round is personal exposure monitoring, an indoor air quality investigation, or regulatory testing of a hazardous material, we scope and ship the sampling kit, review your sampling plan before you collect, and return accredited analysis with each result compared against the limit that applies. Kits ship free to sites anywhere in the United States when AGT Labs performs the analysis.

Defensible, Accredited IH Data
OSHA and litigation attorneys require accredited data. We hold five concurrent credentials — AIHA IHLAP & EMLAP (LAP-101470), NVLAP (101793-0), PJLA (#137751), TX DSHS (#300529), and TX TDLR (#LAB1070) — each publicly verifiable, maximizing your data's evidentiary weight.
100% In-House IH Lab Capabilities
Unlike labs that outsource to subcontractors, we perform all 19 IH testing services directly in our Houston laboratory. This guarantees faster results, tighter QC, and a single point of contact for every project — and it is why your location doesn't change your result.

View IH ServiceHow to Choose the Right IH Testing Lab
Not all industrial hygiene laboratories offer the same scope of accreditation, turnaround capability, or in-house analytical range.
When evaluating an IH lab for your project, verify AIHA accreditation for your specific analytes, check that the accreditation actually covers the method you need — scopes are narrower than most people assume — ensure the lab performs the work in-house rather than subcontracting, and confirm standard vs. rush turnaround options match your timeline.
The AGT Labs IH Lab Guarantee
We check every box. Our AIHA-accredited facility (LAP-101470) serves clients nationwide directly from Houston. We provide a prepaid return label with every sampling kit and assign a dedicated project coordinator to every account, ensuring you never have to chase down a report.
Industries Relying on Our IH Testing Services
Where We Work
We accept ship-in samples from anywhere in the United States. The regions below are where we also run scheduled courier pickup.
Outside these areas? Ship-in works exactly the same.
Every sample is analyzed at the same Houston lab, so a filter from Ohio or Nevada is handled identically to one from Baytown. We ship a kit with a prepaid return label, and samples received before 2:00 PM CST are logged the same day — overnight delivery puts you on the same rush schedule as a local client. Our AIHA-LAP, NVLAP and PJLA accreditations are all ILAC Mutual Recognition Arrangement signatories, so reports are accepted nationwide and in over 100 countries.
Accreditations & Certifications
Each credential is shown with the scope it actually covers — because which methods an accreditation includes matters as much as holding it.
